A nurse is caring for a pancreatic cancer client on a medical-surgical unit who is experiencing marked fatigue and occasional night sweats. For each client finding listed below, indicate whether the finding is commonly associated with radiation therapy only, chemotherapy only, or both radiation and chemotherapy for cancer.

Choice A rationale Fatigue is a universal side effect associated with both radiation therapy and chemotherapy. In radiation, it results from the energy required for cellular repair and the accumulation of metabolic waste from cell death. In chemotherapy, it is often linked to anemia, systemic inflammation, and the cytotoxic effects on healthy tissues. Because both treatments involve systemic or localized cellular destruction and require significant physiological recovery, fatigue is a common finding shared by both modalities. Choice B rationale Night sweats are typically associated with the underlying malignancy itself, such as lymphoma or advanced pancreatic cancer, rather than being a specific side effect of radiation or chemotherapy. While systemic reactions can occur, night sweats are more frequently a symptom of the body's inflammatory response to the tumor or an indication of infection. They are not classified as a standard, predictable side effect of either treatment modality in the same way that cytopenias or enteritis are. Choice C rationale Weight loss is a common finding for both radiation and chemotherapy. Radiation to the abdominal area causes gastrointestinal upset and malabsorption, while chemotherapy induces systemic nausea, vomiting, and alterations in taste. Both treatments can lead to a state of cachexia where the body breaks down muscle and fat stores faster than they can be replenished. Nutritional support is a primary concern for patients undergoing these therapies to combat treatment-induced weight loss. Choice D rationale Pale skin, or pallor, is associated with both radiation and chemotherapy due to their impact on the bone marrow. Chemotherapy is systemically myelosuppressive, leading to decreased red blood cell production and anemia. While radiation is localized, if the treatment field includes bone-marrow-producing areas like the pelvis or spine, it can also contribute to lower hemoglobin levels. Anemia reduces the oxygen-carrying capacity of the blood, resulting in the visible paleness of the skin and mucous membranes.
